So disappointing that I received such a negative attitude and was refused to even speak to someone about a donation. No donation is ever expected but someone being kind and at least passing the request on the the head of the company is not difficult. As for Great HVAC services-- there are some great options without considering this business!

We have used Ambassador several times in the past few years for replacement and installation of malfunctioning parts related to our furnace and air conditioning unit. Recently they provided us free plumbing advice as well to resolve a leak in our bathroom over the phone. They have always been friendly, prompt, professional, and reasonably priced. Would definitely recommend, and have become the first call we make whenever we have an HVAC or plumbing issue.

They over charge ALOT and that's why will never gives an estimate. They charge hourly which is $98.00 (not bad) but a job that can be done with in an hour will take 5 hours. Technician was on phone for an hour to order for the part, Took 1.5 hours to get the part, 30 mins again on phone to get the itemized billing (which I did not requested), they just want to increase the bill amount. They charge a 40% profit on the parts on top of hourly rate of technician plus $ 60 trip charge. I paid more than $ 600 for a simple pipe connector change. Go to other companies that gives a full estimate for the job. Save your money and don't go to them.
